Answer:
The given equation is NOT linear.
Step-by-step explanation:
5x^4+5y = 9
The given equation is NOT linear.
Reason:
A linear equation is defined as the equation for the straight line, where the degree of variables involved is always equal to 1.
But in the given equation :
Degree if x = 4
and degree of y = 1
As degree of x≠ 1 so, the given equation is not linear,
Answer:

Step-by-step explanation:
Each seven-letter word is worth 50 points.
words are then worth
.
Since Sal gets 100 points for playing the game, his points total after
words is
. If he wants to break the record, he must get, at least, 18000 points. "At least" in inequality means
(just as "at most" means
). Then the required inequality is
.
Note that the question says "18000 or more", which is why we used the
symbol. If the phrase had been "more than 18000", we would have used
.
